The hospital records for 100 cases of meningitis in which acute audiometric data has been obtained were reviewed. The incidence of sensorineural hearing loss was found to be 6%. The severity of hearing impairment varied from mild to profound and was frequently bilateral and irreversible. Two-cases showed asymmetrical involvement, and in one case, there was subsequent improvement in threshold sensitivity. Factors that influenced the incidence of neurologic sequela included severity of the initial disease process, age of the patient, and duration of symptoms before diagnosis and treatment. We discuss the pathophysiologic mechanisms that may account for such hearing loss, and we emphasize the importance of early diagnosis and intensive antimicrobial therapy. Careful neurologic evaluation is required after recovery and must include periodic sequential audiometric testing.

1) Etiology of convulsions starting prior to two years of age was discussed in 418 cases. Neonatal seizures before 30 days old appeared in 86 cases (53 boys and 33 girls). Three hundred and thirty-two patients (172 boys and 160 girls) had convulsions in infancy. Twelve patients (9 boys and 3 girls) suffered from convulsions both in neonatal and infantile period. 2)Etiology of convulsions was prenatal in 67 cases (16%), natal in 49 cases (12%), postnatal in 158 cases (38%) and unknown in 144 cases (34%). Prenatal factors consisted of cerebral malformation (23 cases, 6%), associated physical minor anomaly such as cataracta or finger abomaly (11 cases, 3%), abnormal pernatal history (8 cases, 2%), congenital heart disease 3) cases, 1%), tuberose scleorsis (7 cases, 2%) and positive family history (13 cases, 3%). Postnatal causes included hypocalcemia or hypoglycemia (7 cases, 2%), brain tumors (3 cases, 1%), breath-holding spells (21 cases, 5%), febrile convulsion (44 cases, 11%), bathing (3 cases, 1%), afebrile colds (3 cases, 1%), purulent meningitis (17 cases, 4%), DPT immunization (10 cases 2%), vaccination (7 cases, 2%) and acute hemiplegia (10 cases, 2%). The group of unknown etiology were as fns (38 cases, 9%), epilepsy associated with interictal signs (23 cases, 6%), benign infantile convulsions (57 cases, 14%), neonatal convulsion of unknown etiology (12 cases, 3%) and miscellaneous categories (4%). 3) Pregnancy was abnormal in 53% of cases with cerebral malformation. Asphyxia at birth was noted in 43% of patients with tuberose sclerosis and in 35% of congenital cerebral abomaly. 4) Pneumoencephalographic examinations revealed midline anomaly in 50% of cerebral malformation. It was abnormal in all cases with tuberose sclerosis, head injury and epilepsy with interseizure neurological signs. 5) There were no correlations between the seizure pattern and the etiology in neonatal convulsion. In infancy, focal-unilateral convulsions and infantile spasms were frequently associated with organic damages. Generalized seizures were seen in organic lesions as well as functional ones although approximately half of the cases were febrile convulsion, benign infantile convulsion or breath-holding spell. 6) EEG features of cerebral malformation were asymmetrical or multifocal dischages in neonatal period and hypsarhythmia or focal-unilateral spike discharges in infancy. Tuberose sclerosis showed hypsarhythmia in infancy. In birth injury or cerebral anoxia, EEG mostly revealed focal-unilateral abnormality or suppression-burst activity in newborns and hypsarhythmia or focal features in infants. 7) The occurrence rate of neonatal seizures in autopsy cases with intracranial pathology was demonstrated. EEG with intravenous diazepam was useful to know pathophysiology of infantile spasms.

A 9-year old country boy developed blepharitis with inflammation of the face and, 1 month later, eosinophilic meningitis with paralysis of 3 limbs and of an abducent nerve. Nuclear magnetic resonance imaging of the central nervous system disclosed a lesional signal beneath the floor of the 4th ventricle, which was compatible with the presence of a larva of fly. Treatment with thiabendazole was tried, and the clinical signs regressed. Six months later, an asymmetrical hydrocephalus due to obstruction of Monroe's foramen by an inflammatory granuloma was discovered. Human hypodermyasis, due to migration in tissues of larvae of flies, is not rare in cattle-breeding areas. Neuromeningeal disorders are observed in 12% of the cases, consisting of eosinophilic meningitis sometimes associated with neurological deficit or seizures. Such complications as intracerebral haematoma or meningeal haemorrhage may occur during the usually benign course of the disease.

Of 65 cases presenting with neuropsychiatric manifestations of brucellosis (CNS-brucellosis), 9(13.8%) had CT-detected basal ganglia calcification (BGC). Of these, 5 had meningitis and 4 had psychiatric manifestations as presenting features. The diagnosis of brucellosis was made by the finding of consistent history and physical findings and the presence of significantly elevated antibody titres and/or positive culture in the blood and/or CSF. In all the cases, BGC was in the form of punctate hyperdense non-enhancing shadows with average density 44.5-58.4 and maximum density 49-64HU. The calcification was unilateral in 3 cases, bilateral and symmetrical in 4 and bilateral but asymmetrical in 2. None of the cases had other predisposing conditions to BGC and in one of the cases did specific anti-brucella treatment effect a detectable change in the BGC. The finding of CT-detected BGC in patients coming from areas endemic for brucellosis should alert physicians to the possibility of underlying brucellar infection.

Between 1976 and 1984, 11 patients with stab wounds at the craniocervical junction were seen in the Department of Neurosurgery at Groote Schuur Hospital. The injury usually occurred in males, and the left side was predominantly involved. Because of the anatomical features of this region, the penetrating instrument is deflected by the occipital squama into the atlantooccipital or atlantoaxial interspace, and an almost predictable syndrome occurs. The dura mater is penetrated, so that cerebrospinal fluid leakage and meningitis are common complications (meningitis occurred in 5 patients). A meningocele may develop at this site and did occur in 4 patients, but only 2 required surgical repair. Because of the exposed position of the vertebral artery at this level, this vessel was injured in 4 patients; an arteriovenous fistula developed in 2, vertebral artery occlusion occurred in 1, and a false aneurysm developed in another patient. The neurological deficit varied in magnitude, was often transient, affected the upper limbs more than the lower, was asymmetrical (suggestive of lateralized injury), and at times showed a remarkable tendency to recover. Awareness of the existence of this syndrome may help in forestalling complications. The only warning sign may be an insignificant wound in the suboccipital or retromastoid region.

The age specific incidence of the palmomental reflex (PMR) has been investigated in persons without any former or present evidence of a neurological or mental involvement. Also excluded were persons with hypertension, diabetes mellitus, thyroid dysfunction, alcohol abuse and other diseases as these could effect the central or peripheral nervous system. From the newborn period up to the age of 20 years the incidence of the PMR was between 3,3% and 20%, the differences being statistically insignificant. After the age of 20 years the incidence of the PMR rises with increasing age, the rise being approximately 10% per decade. There was no asymmetry of the PMR in persons without affection of the nervous system and who met the above mentioned criteria. Since a symmetrical PMR can be found in a considerable percentage of persons with no indication of a neurological or mental involvement, it should not be considered as a pathological sign. An asymmetrical PMR was found in 20 persons who did not meet the above mentioned criteria. In 5 out of these 20 persons additional neurological signs could be detected. 9 patients had histories of brain trauma, meningitis, cerebrovascular disease and polyneuropathy. 9 others were suffering from severe cardiovascular disease, carcinoma and alcohol abuse. In only one patient, although presenting with some neurological signs, no relevant history could be detected. An asymmetrical PMR, therefore, must be considered as a discrete indication of an involvement, either of the central or the peripheral nervous system. The PMR has no certain localizing significance.

The authors sent a circumstantial questionnaire to 224 surviving patients out of a 228 unilateral acoustic neurinoma operated on from June 83 to December 90 range of patients in order to assess their complaints. Seventy-two per cent of these neurinomas were Stade III or IV of Koos. Translabyrhintine approach was used for 85% and suprapetrous approach for 15%. The post-operative mortality rate is 1.75%. At the end of the procedure, the removal seemed total in 99% of cases and the anatomical facial nerve continuity was preserved in 94% of cases. Our patients kept or recovered a normal (Grade I of House--52%) or almost normal (Grade II of House--14%) facial motion in 66% of cases. A normal facial rest stretching with a complete eyelid closure but an asymmetrical facial mimic (Grade III of House) were in 20% of cases, and a more important facial palsy with incomplete eyelid closure was in 4% of cases (Grade IV of House). Patients needed an hypoglosso-facial anastomosis in 10% of cases. Always, this anastomosis restored a good facial motion near the Grade III of House. Hearing preservation was achieved for 45% of the attempts (through a suprapetrous approach) but hearing so preserved was functional (pure tone loss less than 50 db) in 37.5% of cases (5% of all the patients of this series) and only 61% of these patients kept or recovered a normal or almost normal facial motion. Varying, often regressive, complications were observed: C.S.F. leakages (7.5%) through the operative wound in two third of cases, owing to a pressure raising due to meningitis or C.S.F. circulatory constraint and usually cured by lumbar punctures and, if need be, antibiotics and, in one third of cases, through the tympanic cavity then nostril because of a hole remaining on the petrous drilled wall and usually needing a reintervention, swallowing difficulties (3%), due to a contralateral vagus nerve palsy in half of cases, postoperative hematomas (1.75%), fatal in one out of two times, brain traumatism (1.75%), meningitis (0.4%). The answers of patients were proper enough to be used for this study in 80% of cases (178). Their subjective answers about facial motion agreed with our objective assessment in 84% of cases that is emphasizing the difficulties of all attempt to this type of valuation. Our patients point out balance troubles in 67% of cases.(ABSTRACT TRUNCATED AT 400 WORDS)

Listeria monocytogenes rhomboencephalitis is an uncommon complication of L. monocytogenes meningitis. It presents in a typical biphasic pattern characterized by a non-specific prodromal period followed by any combination of asymmetrical, cranial-nerve palsies; cerebellar signs; hemiparesis or hypesthesia; and diminished consciousness. The survival rate is greater than 70% when appropriate antibiotic therapy is initiated early. However, approximately 60 percent of the survivors develop neurological sequelae. We present the case of a 33-year-old woman who developed L. monocytogenes meningitis with subsequent rhomboencephalitis and cranial-nerve palsie, and review the literature on this syndrome.

We report a case of central European tick-borne encephalitis with cervical myelitis presenting clinically as a lower motor neuron syndrome of the upper limbs with proximal asymmetrical pareses and atrophies. There were no sensory deficits nor signs of lesions of the spinal pathways or signs of encephalitis or meningitis. The affected motor fibers of the upper limbs were electrically inexcitable, but sensory findings were normal. Electromyography of the paralyzed muscles revealed pathological denervation activity without voluntary activation. The initial magnetic resonance imaging (MRI) showed a large hyperdense lesion in the anterior part of the cervical cord from C3 to T1. Despite the fact that MRI changes disappeared completely within 6 weeks the patient showed only little improvement in the paralyzed muscles after 6 months. To our knowledge, these MRI changes in patients with tick-borne encephalitis, consistent with an isolated anterior horn lesion, have never been reported previously. The course may have been aggravated by an initial antibiotic treatment with cephalosporins.

Eosinophilic meningoencephalitis (EME) has been described in various species of animals and in humans. In dogs it has been associated with protozoal infections, cuterebral myiasis and various other aetiologies. Ten cases of idiopathic eosinophilic meningoencephalitis have been reported in dogs and one in a cat where the origin was uncertain or unknown. The dogs were all males, of various breeds but with a predominance of Golden Retrievers and Rottweilers; they generally had a young age of onset. Two cases with no apparent underlying aetiology were diagnosed on post mortem examination. The 18-month-old, male Boerboel presented with sudden onset of cerebellar ataxia, as well as various asymmetrical cranial nerve deficits of 2 weeks' duration and without progression. Haematology revealed a peripheral eosinophilia. Necropsy showed extreme generalised congestion especially of the meninges and blood smear and histological sections of various tissues showed intravascular erythrocyte fragmentation with the formation of microcytes. Histopathology revealed severe diffuse cerebrocortical subarachnoidal meningitis and submeningeal encephalitis, the exudate containing variable numbers of eosinophils together with neutrophils and mononuclear cells. There was also deeper white matter and hippocampal multifocal perivascular mononuclear encephalitis and multifocal periventricular malacia, gliosis and phagocytosis of white matter. The cerebellum, brain stem and spinal c showed only mild multifocal oedema or scattered occasional axon and myelin degeneration respectively, with no inflammation. Immunohistochemical staining of central nervous tissue for Toxoplasma gondii failed to show any antigen in the central nervous tissue. Ultrastructure of a single submeningeal suspected parasitic cyst showed it to be chromatin clumping within a neuron nucleus indicating karyorrhexis. Gram stain provided no evidence of an aetiological agent. The 3-year-old Beagle bitch had a Caesarian section after developing a non-responsive inertia 8 days prior to presentation. This animal's clinical signs included status epilepticus seizures unrelated to hypocalcaemia and warranted induction of a barbiturate coma. She died 4 hours later. Post mortem and histopathological findings in the brain were almost identical to those of the Boerboel and she also showed histological evidence of recent active intravascular haemolysis with microcyte formation. Rabies, distemper and Neospora caninum immunohistochemical stains were negative in the brains of both dogs. Immunohistochemical staining of the cerebral and meningeal exudates of the Beagle for T- and B-lymphocyte (CD3 and CD79a) markers showed a predominance of T-lymphocytes with fewer scattered B lymphocytes. A possible allergic response to amoxicillin/clavulanate is considered, as this appeared to be the only feature common to the recent history of both animals. An overview of EME in humans, dogs and cats is given and the previously published cases of idiopathic EME in dogs and the single published cat case are briefly reviewed.
